Method and apparatus for platooning of vehicles

ABSTRACT

Platooning vehicles can result in operational cost savings. Disclosed is a method of apportioning costs that are incurred/saved as a result of platooning vehicles, as well as assigning penalties for unfair platoon participation. For example, platooning history of a vehicle can be tracked, and if that vehicle acts too often as a trailing vehicle in a series of platoons then a penalty might be assigned to that vehicle. Also disclosed is a technique for operating a platoon in the presence of external factors such as municipal regulations, merging traffic, emergency vehicles, etc.

TECHNICAL FIELD

The present invention generally relates to platooning of vehicles, and more particularly, but not exclusively, to platooning vehicles to account for cost and/or operational considerations.

BACKGROUND

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 depicts an embodiment of platooning vehicles.

FIG. 2 depicts an embodiment of an apparatus useful to operate a platoon of vehicles.

DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS

For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications in the described embodiments, and any further applications of the principles of the invention as described herein are contemplated as would normally occur to one skilled in the art to which the invention relates.

With reference to FIG. 1, there is illustrated a schematic view of an example vehicle system 100 including an engine 102, such as an internal combustion engine, structured to generate power for the vehicle system 100. The vehicle system 100 can sometimes be referred to herein as a truck, or tractor-trailer semi, etc for ease of convenience, but no limitation is hereby intended to limit the system 100 to a truck, or tractor-trailer semi, etc. Thus, the term vehicles system 100, truck, tractor-trailer semi, or other vehicle designation is intended to cover a wide range of vehicles such as trucks, tractor-trailers, box trucks, busses, passenger cars, etc. The vehicle systems 100 illustrated in FIG. 1 are depicted as tractor trailers, but any type of vehicle is thus contemplated herein. Several vehicle systems 100 are illustrated in a platooning operation in which the vehicles act together to reduce overall fuel costs and improve operation. Although only three vehicle systems 100 are illustrated, any number of vehicles can be used.

Platooning vehicles can be described as a state where a series of tractor-trailer semis are linked together by telematics or GPS where the units or engines communicate to transverse in a line as an operational cost efficient strategy. The lead vehicle may be equipped with aerodynamic capability (wind assist panels on cab & trailer, aerodynamic tractor body) that creates a laminar flow of air (tunnel effect) that greatly reduces air drag. The following semis are spaced close enough to the lead vehicle taking advantage of the “tunnel” increasing fuel economy.

The vehicle system 100 can include a controller 104 used to regulate various aspects of the platooning arrangement depicted in FIG. 1 and discussed herein. The controller can be a single device or alternatively composed of a number of separate devices acting in concert. The controller 104 can be comprised of digital circuitry, analog circuitry, or a hybrid combination of both of these types. Also, the controller 104 can be programmable, an integrated state machine, or a hybrid combination thereof. The controller 104 can include one or more Arithmetic Logic Units (ALUs), Central Processing Units (CPUs), memories, limiters, conditioners, filters, format converters, or the like which are not shown to preserve clarity. In one form, the controller 104 is of a programmable variety that executes algorithms and processes data in accordance with operating logic that is defined by programming instructions (such as software or firmware). Alternatively or additionally, operating logic for the controller 104 can be at least partially defined by hardwired logic or other hardware.

Turning now to FIG. 2, there is illustrated an exemplary electronic control system 104 useful to control various aspects of one or more of the vehicle systems 100 as well as the platooning techniques described herein. In one form the electronic control system 104 is included in each individual vehicle system 100, but in some forms the electronic control system 104 will be understood to be the collective control functionality as the systems 100 cooperate to platoon using the techniques described below.

The electronic control system 104 can include one or more of the following (depending on the capabilities of any given vehicle system 100): an engine control module (ECM) 106, vehicle operator input (VOI) system 108, human-machine interface (HMI) system 110, GPS system 112, vehicle-to-X communication (V2X) system 114, vehicle proximity sensor (VPS) system 116, and a calibration interface 118 which supports communication with an electronic system calibration tool. It shall be appreciated that system 108 is an example of a system structured to provide operator input via one or more vehicle controls that is used to control the vehicle. It shall be further appreciated that systems 110, 112, 114, 116, and 118 are examples of systems that are structured to receive information from a source external to a vehicle system which relates to vehicle environment factors, location factors, mission factors, warranty factors (e.g., component residual life, component replacement cost and component replacement time), operator-specified factors, and/or fleet-specified factors. System 300 may also include a number of additional or alternate systems and/or additional or alternate inputs.

VOI system 108 provides information pertaining to vehicle operator control commands to ECM 106. The provided information may include brake pedal position information, accelerator pedal position information, cruise control setting information, and other information provided by a vehicle operator via one or more vehicle control devices or systems. ECM 106 may process the received information to determine additional information including, for example, brake pedal position rate of change information, brake pedal actuation frequency information, accelerator pedal position rate of change information, and accelerator pedal actuation frequency information. In certain embodiments such additional information by be determined by VOI system 108 prior to being provided to ECM 106.

ECM 106 may utilizes the information received from system 302 in determining commands for controlling various operational aspects of vehicle system 100, for example, engine control commands, fueling control commands, transmission shift commands, and brake actuation commands, among others.

HMI system 110 includes a human-machine interface through which a vehicle operator or another person may provide additional information from a source external to the vehicle system. The human-machine interface may comprise a touch screen display, keypad or other device through which information may be input. The human-machine interface may also comprise a wireless communication system allowing a person remote from the vehicle to input information. The provided information may include information relating to the existence and/or duration of extended idle conditions, mission performance parameters (e.g., mission route, mission length, length or duration of certain mission activities, platooning or convoying opportunities, route planning, and weather or traffic planning), requirements for shore power (e.g., auxiliary power unit (APU) devices such as no-idle climate control systems or other power take off (PTO) devices), among other information. The provided information may include information related to warranty factors including, for example, residual life of one or more components, replacement cost for one or more components, and replacement time for one or more components. The provided information may include information related to operator-specified factors including, for example, fuel cost, diesel exhaust fluid (DEF) cost, fuel and/or DEF availability, fuel and/or DEF supply or purchase agreements, sociability constraints, peak performance requests, and on/off-road use, among others. The provided information may include information related to fleet-specified factors including, for example, emissions banking and credit trading, load management, and customer or fleet operator preferences.

GPS system 112 provides information pertaining to vehicle location to ECM 106. The vehicle location information may be received by a receiver of system 306 as a wireless signal from a satellite-based global positioning system. The received information may be provided to ECM 106 in the form received or may be pre-processed to decode or change the format or organization of the received information.

V2X system 114 provides information received from one or more external sources to ECM 106. The information may be received by a receiver or transceiver of system 114 as a wireless communication signal from a variety of different sources equipped with a wireless transmitter or transceiver including, for example, other vehicles, traffic lights and other traffic signals, utility grid devices or systems, stationary transceivers in communication with other communication networks and remote servers or human-staffed computing systems also in communication with the other communication networks. The provided information may include information related to road or traffic signal conditions, information related to weather conditions, information related to warranty factors including, for example, component residual life, component replacement cost and component replacement time, information related to operator-specified factors including, for example, fuel cost, DEF cost, fuel availability, fuel agreements, sociability constraints, peak performance requests, on/off-road use, information related to fleet-specified factors including, for example, emissions banking and credit trading, load management, and customer or fleet operator preferences.

V2X system 114 may be utilized in connection with intelligent transport systems (ITS) which comprise systems that integrate of information and communication technologies with transport infrastructure to improve economic performance, safety, mobility and environmental sustainability. An exemplary ITS system includes three operational layers: a data collection layer, a data aggregation and translation layer and an information dissemination layer. The data collection layer may include one or more elements of electronic control system 104 as well as devices and systems on a plurality of vehicles which sense and transmit data associated a plurality of vehicles at particular geographical locations. The data collection layer may further include sensors, cameras and other data sources which are fixed relative to a roadway, or information from sensors, cameras and other data sources which are provided on surveillance vehicles such as planes and helicopters.

The data aggregation and translation layer comprises one or more computer based systems which receive and aggregate data from the data collection layer devices and process the received data to provide information about one or more roadway or traffic conditions. In certain aspect, the received data may include information about road grade, vehicle rate of speed, or change in rate of speed at particular locations which may be aggregated and processed to determine traffic speed over a given segment of roadway. In other aspects, information about weather conditions such as wind speed, precipitation and road conditions may be derived.

The information dissemination layer may include one or more elements of electronic control system 104 as well as devices and systems on a plurality of vehicles which receive information transmitted from the data aggregation and translation layer. The received information may include road grade information, information about traffic speed over a given segment of roadway, as well as information about weather conditions such as wind speed, precipitation and road conditions may be derived. ITS information from one or more of the foregoing layers may be received by system 114 and provided to ECM 106.

Proximity sensor system 116 provides information pertaining to other vehicles or objects within a sensor range to the vehicle to ECM 106. The provided information may include distance to one or more vehicles 100 or objects in sensor range, velocity of one or more vehicles 100 or objects in sensor range and acceleration of one or more vehicles 100 or objects in sensor range. ECM 106 can include an engine controller 120. ECM 106 may also include additional or alternate controllers including, for example, transmission controllers, aftertreatment system controllers and vehicle system controllers, among others. ECM 106 is structured to provide one or more inputs received from systems 108, 110, 112, 114, 116, and 118 to the controller 120.

Engine controller 120 may be structured to control a number of aspects of the operation of the engine 102 and other associated elements of vehicle system 100 including, for example, air handling, provision of a first fuel type and exhaust aftertreatment, among others.

One or more of the aforementioned systems (ECM, VOI, HMI, GPS, V2X, VPS, calibration interface, engine controller), and/or other useful systems, can be used to exchange information between the vehicle systems 100 participating in the platoon. In one non-limiting embodiment, the systems mentioned above and/or other useful systems can be used to record fuel usage of the vehicle system 100 during operation. In some forms, the fuel usage recorded can be archived for later data analysis. Recordation of fuel usage and/or other measures of vehicle system 100 operation can be indexed to a specified course, whether the vehicle system 100 was participating in a platoon, what position of the platoon, atmospheric conditions at the time of recordation, etc. Such information can be useful in developing a scheme to compensate participants in a platoon (whether that be via financial compensation, compensation by preferred location in a platoon, etc) and/or can be used to penalize vehicles, particular drivers, or organizations (e.g. a vehicle fleet) that attempt to extract benefits without sharing costs. Other schemes that can benefit from the exchange of information made available via the various aforementioned systems can include platoon formation management (e.g. when to split the platoon for merging traffic purposes, etc).

Turning now to one aspect of the platooning operation of vehicle systems 100, using knowledge of locations, velocities, destinations and available hours of each of the vehicle systems 100 in a platoon (or alternatively candidates for a platoon), could permit in one embodiment the ability to direct a specific vehicle system 100 to platoon behind another and then, once in formation, use information of the first (such as, but not limited to speed and throttle characteristics) to ensure appropriate following of the second. Other information could also be used such as but not limited to inter-vehicle distance. When in a platooning arrangement, additional fuel burned by the first vehicle system, and any less by the second, can be determined (e.g. by using systems described herein), since access to relevant information is available (e.g. relevant information of the individual power trains). A baseline of fuel burn information could be determined from data from prior vehicle systems traveling that same route, coupled with atmospheric conditions and vehicle weight. Utilizing that information, the second truck in the platoon could be charged a fraction of their particular fuel savings while participating in the platoon as payment for services and compensate the lead truck for any additional expenses. The platooning history of these trucks could also be tracked in order to ensure equal instances in front or back. It will be appreciated that the information discussed above can be shared and acted upon by a controller, such as controller 104.

The platooning algorithm (which will be understood to be capable of execution on a controller, e.g. controller 104) could additionally and/or alternatively implement a model similar to a peer-to-peer sharing model. In this model, the platooning algorithm could keep track of the amount of benefit a truck has received and/or what has given up. Based on this information, trucks could be re-arranged within a platoon or this information could be used to determine the placement of the trucks in the next platoon they join. In addition, for trucks that consistently receive benefits of being a following truck without ever being the lead truck (referred to as “leeching” in computer terminology), the offending truck may have actions taken such being flagged on a fleet management report or platooning capabilities disabled for a set time or other actions.

Additionally and/or alternatively, that platooning service can be structured such that an entity that uses the platooning service without providing back to the group could eventually lose privileges and potentially be disallowed from the group. There are a few avenues with which a fleet or owner/operator could maintain equitable status and avoid this situation. One involves being a platoon leader on occasion, or having a sister truck within the fleet be the platoon leader. In this way a fleet could be treated as a whole in lieu of an individual truck, and the equitable treatment assessed across the entire fleet. Another approach to equitable participation would be to offer to be the break point in the platoon should an exit come up and the platoon needs to split for traffic maintenance (described more fully below). Another approach would be to pay a fee. Each of these approaches will be understood as being capable of implementation on a controller, such as controller 104.

The honest status of each truck/fleet can be maintained in a few ways. One is for a third party platooning service or hub to monitor subscribed accounts that keep track of the involvement and value add of each truck and/or fleet and make credits/deductions from an account based on predetermined group policy. A second method, that follows more closely to P2P networking, is for each truck to broadcast its own status, policy and history, and a shared group policy is then adhered to. Each of these approaches will be understood as being capable of implementation on a controller, such as controller 104.

Designations about which position the respective vehicle systems 100 will have within a platoon can be negotiated from vehicle to vehicle, or in some forms can be determined remotely and communicated to the vehicles. For example, a central server could receive and coordinate platoon requests/invitations and then issue commands (such as through the ITS) regarding which position the various vehicles should take. Furthermore, the compensation and/or costs/penalties described above can also be coordinated through the central clearinghouse described above (e.g. a central server) and communicated through the ITS.

In another additional and/or alternative embodiment, the size/length/arrangement of platooning vehicles can be actively managed (collectively or through a central server issuing instructions) depending on circumstances as they occur during travel of the platoon. It will be understood that such active management can be implemented in a controller, such as controller 104. The platoons can be split up or broken into one or more smaller units. Such a breakup might still result in the trucks operating as a loose platoon (e.g. with rather larger inter-vehicle distances separating each truck) until such time that the platoon can be reformed. Other breakups may result in a designation of operation in which one or more trucks is not included in the platoon and can float to whatever distance is best suited for the truck, until such time that the platoon can be re-engaged. The number of trucks in the platoon might be limited based on the influence of combination of factors. In the US, each state legislates the combination type of rearward amplification of vehicles (tractor-trailer, doubles, triples, straight truck with trailer, 5 axles, 3 axles, Rocky Mountain double, conventional double, Triple, California truck full trailer, turnpike double, etc). A platoon has a minimum length of 2. The maximum length may depend on one or more of the following: type of trailers in the platoon, state regulations (which may be detectable via GPS and database/table), operating environment (urban/rural, type of road—#lanes), determination if there is a fuel consumption benefit to the truck, road conditions (construction, weather), type of cargo (hazmat, flammables) and, if used on secondary roads (railroad crossings, traffic signals), among potential others.

The following set forth just a few examples of circumstances which might require active management of the platoon configuration:

-   -   1. The one or more vehicles in the platoon can have the ability         to sense interstate exit or entrance ramps via GPS or sensing         equipment where such knowledge allows the platoon to separate a         distance before the ramps to create gap in the semis allowing         traffic to flow between the line of trucks. The distance and gap         may be calibratible and may have dependencies on vehicle speed,         road conditions, and traffic density. After the passing of the         entrance ramp, the lead truck slows allowing the platoon to         reform back to the original status while sensing intermediate         traffic and allow traffic to move out from between the platoon;     -   2. Detection of a municipality prohibiting platooning, which may         include length restrictions and/or restrictions during certain         hours/days. Such restrictions may require temporary change in         platoon configuration until the municipality has been passed;     -   3. Emergency personnel and/or vehicles having the capability to         communicate to the platoon that it needs to cut in and/or that         vehicles from other lane(s) need to cut in so that the emergency         vehicle can pass by;     -   4. Detection of the vehicle in the other lane(s) is drifting         lanes (or a turn signal from the vehicle in the other lane), the         platoon can temporarily separate until the vehicle passes the         former platoon;     -   5. Passenger or other vehicles have the ability to communicate         to the platoon that they want to turn and the platoon separates.         The trucks could also sense the turn signals on the other         vehicles and then initiate a separation of the platoon (and         possible re-engagement of the remaining trucks);     -   6. Detection that a truck cannot keep up with the platoon         (engine malfunction, not having the power in the mountains, no         tire chains, need to pull off for fuel/DEF, length of driver         shift) and having it break out. Truck could broadcast this         information to the others in the platoon or the other trucks in         the platoon could sense;     -   7. Determining that one or more trucks of the platoon will need         to be re-routed—bridge height restrictions, bridge load         restrictions, cargo type (in some instances the first truck in         the platoon may communicate road information sign such as these         to the other trucks);     -   8. Advance notification to the platoon management on truck(s)         taking different routes (e.g. a truck to be diverted to another         route will signal to the other trucks of its intention to leave,         or in the alternative it's platoon route will have been defined         prior to joining the platoon such that the end point of its         platoon travels will have been known in advance to the remaining         trucks); and     -   9. Detection of traffic density (e.g. when detecting heavy local         traffic the platoon can either terminate or split allowing wider         distances between platoon members until the traffic density         abates).         One or more of the aforementioned circumstances can give rise to         management of platoon configuration. These circumstances can be         detected by one or more of the onboard systems described herein         (HMI, V2X, etc), and can also be communicated via ITS. Once the         circumstance is detected by the platoon management system,         active control of the platoon configuration can commence.         Commands or requests can be generated to separate the platoon         into larger inter-vehicle distances and possibly break the         platoon until a possible later engagement.

Active management of platoon configuration can be facilitated through knowledge sensed by one or more vehicles in the platoon or communicated to/from the platoon, for example:

-   -   1. Platoon broadcasts to the environment (police, emergency         equipment, other vehicle, . . . ) information such as road         conditions—weather, construction, accident;     -   2. Others (police, emergency, . . . ) can broadcast to the         platoon—road conditions, accident, weekend events impacting         traffic density (e.g. a heavy traffic sporting event such as the         Indy 500);     -   3. When a platoon is in progress, all of the trucks have their         headlights/taillights are on. Alternately, have some sort of         visual indicator to indicate to other vehicles on the road a         platoon is in progress.         Platoon management algorithms hosted in any of the devices         described above (e.g. HMI, V2X, ECM, etc) can account for any of         the circumstances described above. Thus, the platoon management         algorithm can account for municipality restrictions, emergency         vehicle needs, etc. The algorithm can furthermore be hosted in a         device off vehicle in a central server where commands are then         sent out to the vehicles in the platoon. Additionally and/or         alternatively, the algorithm can reside in each vehicle and         inter-vehicle communication can commence to negotiate how the         trucks in the platoon will break/reconfigure/etc.

It will be appreciated in this written description that any of the above features (e.g. features related to financial cost or benefit, features related to expanding the platoon to permit passage of vehicles or accommodate other road conditions, features related to breaking of the platoon and possible reforming, etc) can be combined with any of the other features in any given embodiment, though it may not be explicitly described in that manner. Thus, in some embodiments one or more features from within one or across the various set of features discussed can be included in any given embodiment. Thus, although the features are discussed separately for ease of simplicity, no limitation is hereby intended regarding any potential combination.
